ragdoll
Is there a way to make a ragdoll like character. If so, would you need separate entities and then attach them. or use another method? And if you use constraints how do you make it so the model is able to move? ~(anchor point stop movement)
This has been asked many times, please use the search button
..yes, you can make ragdoll physics in 3DGS

I have used the search feature but most of the posts are out dated or lack information so i created a specific thread on ragdoll. Plus, when i said is there a way i was asking for an example for the code. sorry if this wasn't seen in that way.

well, what part of code interests you?
The section to attach physics objects to a bone ready model which moves segments accordingly. any code will surely help.

If someone can tell me how to place a bone on a modelsposition I´m done with my (hopefully easy to use) ragdollsystem...
It would be great if someone could help me
Thanks,
Slin

well, last time i've done it i had no probems. i'll post code if i'll have time
I really badly need that code

ENTITY* create_bone(ENTITY* ent, STRING* parent, STRING* child)
{
VECTOR parent_pos;
VECTOR child_pos;
ANGLE bone_ang;
ENTITY* temp_bone;
vec_for_bone(parent_pos,ent,parent);
vec_for_bone(child_pos,ent,child);
vec_sub(child_pos,parent_pos);
vec_to_angle(bone_ang,child_pos);
temp_bone = ent_create("crate.mdl",parent_pos,0);
vec_set(temp_bone.pan,bone_ang);
temp_bone.scale_x = 0.1;
temp_bone.scale_y = 0.1;
temp_bone.scale_z = 0.1;
return(temp_bone);
}
use it like this
create_bone(doll,"ValveBiped.Bip01~17","ValveBiped.Bip01~18");
you = create_bone(doll,"ValveBiped.Bip01~30","ValveBiped.Bip01~31");
create_bone(doll,"ValveBiped.Bip01~11","ValveBiped.Bip01~12");
wait(-7);
ent_remove(you);//remove 2nd bone in 7 seconds for testing
Thanks for that code. I have modified it so it can work with my game. I do have another question. How do you update the bones position and angle according to where the new models position is?
I have enabled physics on each of the new models (at each bone parent) but I cant figure out the code to update the bone position on the model according to the parent position models.
Each parent model has its own action.
How do you update the bones position and angle according to where the new models position is?

This is the only point I´ve got some problems with. I´m already done with creating the skeleton out of single physikentities.The problem isn´t really the angle but the the position. Each physikentity has it´s own action and "knows" the name of the bone it is placed on.
Thanks,

I also have the same problem. The hand book says you must reset the bone first if you want to set it to a certain position. I do this and it still returns strange figures.

Re: ragdoll - 08/29/07 01:45
are the physics ents constrained?
also, you dont HAVE to reset it. thats for combining multiple animations using ANM_ADD
for this you might want to check out the part of the lite-c workshops in the chapter on advanced uses for bones. Intstead of setting bones to entity positions, change the ANGLES to point the bones at their associated entities
o.k. I set you "programmers" a challenge. I bet you can't do it.
1. Create a box with one bone with all verts attached. (main box 1 should be bigger than box 2)
2. Create a second box with one bone and all verts attached. (box 2)
3. Create a large box which has physics enabled. (box 3 should be bigger than box 1)
4. Create a level and put the large box about 5000 quants on x.
5. Place box 1 at position 0,0,0 and make it passable and transparent.
6. Place box 2 at position 0,0,0 and enable physics on this box.
7. Create a short function to send box 3 towards 0,0,0 (minus X). Function should run on a key press.
8. Write a script to update the position and angle of box 1 using the bone only. Use ent_bonemove, ent_bonerotate and ent_bonereset. Box 1 should equal the position of box 2.
If you done it how I have then you should notice that ent_bonemove doesnt seem to work properly. If not then you have a different problem or you are a true programmer for 3D Gamestudio and would you please send me the project with code.
I have only gone and cracked the problem. I followed my own instruction as from the last post lol. I recreated a game and ran some tests. The problem with ent_bonemove is that it takes the scale of a model into account. (THIS SHOULD BE STATED IN THE MANUAL) If both models have the same scale then the can both equal the same co-ordinates. I guess ent_bonemove must devide all values in the vector (that are returned) by the scale of the model.
edit: Just found out another thing... ent_bonemove also relys on the origin. Rather than the actual bone position.

You solved it? congratulations!
it'll be interesting to see a video

@ frescosteve: If it should be stated in the manual, maybe you can post the info at Blame the Manual forum. Could be helpful to others I guess!?
I have posted on the Blame the Manual forum. I have also posted on the tutorial forum asking for a detailed tutorial in creating a fully working rag-doll.

How do you want to use the ragdoll?
Is it a Human, that if you kill him he turns into a ragdoll and falls together?
Then thats cool.

Guys, why you don`t wont use my Physics constrains editor,
I created PCE special for creating ragdoll and other ODE physics constrains.
My labour is unavailing really!

well, i got impressed by the editor, but at first look i couldnt use it.

Quoting MDMDFSS.

Probably, some version was entered in the contest, and seemingly that version won 2nd place.
